Start-up preparation: every time the CNC machining center is turned on, or after the machine tool presses emergency stop to reset, it will first return to zero, so that the machine tool has a reference position for future operations.
Clamping work: Before working and clamping, all surfaces should be cleaned first, and there should be no impurities such as oil, iron filings, dust, etc., and at the same time, files or oilstones should be used to remove burrs on the surface of the workpiece.
The high-speed rail used for clamping must be smoothed by a grinder before it can be used. The code iron and nut must be fastened. For some small workpieces that are difficult to clamp, we can directly clamp them on the tiger. The workbench of the CNC machining center should be clean, and there should be no oil stains, iron filings and other plantings. The shim should be placed on the four corners of the workpiece. For large-span workpieces, we need to put a contour shim in the middle .
According to the specific dimensions of the drawing, use a drawing ruler to check whether the length, width, and height of the workpiece are in the qualified stage.
During the clamping process of the workpiece, the operation should be carried out according to the clamping and placement method of the relevant instructions of the CNC machining center. At the same time, it is also necessary to consider the position of avoiding the machining and the tool head may touch the fixture during the machining process. Happening.
When the workpiece is placed on the horn, the reference plane of the workpiece must be drawn according to the drawing requirements of the CNC machining center, and the verticality of the workpiece must be checked for compliance.
